"Is it because you're blind?" she asked, and that was - not what he'd expected. He laughed because he was nervous; he laughed because he knew she was watching him, and he didn't want her to think that she'd found a weak point.

This is relevant to my interests! lol

Does he show up there with his cane, and make a show of still using it? Does he still orient himself? Or does he drop all pretences?

They must be wondering if he's really blind (and if so, exactly by how extensive is it? How does he do the things he does?).

Also, there's the more benign curiosity of getting to know someone who's blind and the things he does differently.
